本研究评估了沙特阿拉伯西南部山区五种未被充分利用的野生水果（Coccinia grandis (L.)）的营养价值、生物活性成分和抗氧化活性。Voigt, Diospyros messpiliformis Hochst。A.Dc交货。，圆叶仙（L.），麻黄。和格雷维亚·维拉萨·威尔德)。测定其含水量、粗纤维、总蛋白质、总脂质、总水解碳水化合物、总可溶性糖和总游离氨基酸。结果显示，五种研究物种的果实中含有不同的含量。此外，还评估了矿物质组成、氨基酸含量、酚类化合物、维生素和抗氧化活性。总酚和总单宁含量最高的是中螺螺，分别为20.69 mg/g和3.84 mg/g，最低的是粪肠，分别为10.83 mg/g和1.44 mg/g。甲醇提取物（1 mg/ml）对DPPH自由基的清除率较高（87.36%）。甲醇提取物（1 mg/ml）的总抗氧化活性和过氧化氢清除活性最高（71.53%）。这些野果具有丰富的营养和抗氧化价值，为当地居民提供了健康的食物来源，与许多栽培的水果和蔬菜一样。
This study evaluated nutritional values, bioactive constituents and antioxidant activities of the five wild underutilized fruits in the mountains of southwest Saudi Arabia (Coccinia grandis (L.) Voigt, Diospyros mespiliformis Hochst. Ex A.Dc., Cissus rotundifolius (L.), Ephedra foeminea Forssk., and Grewia villosa Willd.). The moisture content, crude fibers, total protein, total lipids, total hydrolyzable carbohydrate, total soluble sugars, and total free amino acids were analyzed. The results showed varying amounts among fruits of the five study species. In addition, the mineral composition, amino acid content, phenolic compounds, vitamins, and antioxidant activity were assessed. The highest content of total phenolic and total tannins was measured in D. mespiliformis (20.69 mg/g and 3.84 mg/g) and the lowest in E. foeminea (10.83 mg/g and 1.44 mg/g), respectively. The methanol extract (1 mg/ml) of D. mespiliformis displayed higher percentage of DPPH radical scavenging activity (87.36%). The methanol extract (1 mg/ml) of C. grandis exhibited the highest effect of total antioxidant activity and hydrogen peroxide scavenging activity (71.53%). The sufficient nutritional and antioxidant value of these wild fruits provide healthy food source for the local residents, much the same as many cultivated fruits and vegetables.
